Abstract

These days, unpredictable climate change occurs at anytime and anyplace without our consciousness that could affect our lives miserably through natural disaster or severe illness. This is where weather station that equip with IoT come into place where people can monitor real time weather data through smartphone device within WiFi connectivity. These systems are intended to keep an eye on critical occurrences in the physical world, producing information that can be uploaded to the cloud where it can be accessed by applications and from which early precaution can be taken. This project employs 32-bit microcontroller, anemometer sensory part, ESP32 Wi-Fi module where data sends transmissions to cloud service which is Blynk server where it is processed and stored. An application which is Blynk IoT can connect to the intended device to show users the rcorded weather data through smartphone. Therefore, wind vane and 3 cup anemometer has been calibrated against reliable tools to ensure their preciness before installing weather station outdoor for analysis purpose. The wind speed of this weather station has been verified against digital anemometer and has percentage error less than 5%. Wind direction has been verified through digital compass to calibrated its accurateness of direction. The data is collected, analyzed and compared with other weather forecast website like Zoom Earth which is a live weather satellite, Public InfoBanjir, and Malaysian Meteorological Department. These are the most reliable source for weather guidance whether locally or globally for public who keen to know about regional weather status. This product is designed to withstand such blustery weather condition in a long run. Thus, having this personal weather station equipment at household is pretty convenient to monitor real-time weather.
